J WILLIAM'WARREN, OF KANSAS CITY, MISSOURI.

ADZING 'MACI-IINE.

To all 10720112. it may concern.

Be it known that I, J VVILLIAM \VARREN, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented new and useful Improvements in Adzing Machines, of which the following is a specification.

'This ii vention relates to an adzing machine for railroad cross ties, the general object of the invention being to form seats for the rails which will cause the rails to set at an incline and counteract the tendency of the weight and pressure of the trains upon the rails to cause the rails to assume a position where they incline outwardly. This invention is an improvement over the device illustrated in Patent No. 1,300,064, dated Apr. 8, 1919.

Another object of the invention is to make the device self-propelling and to provide means for regulating the degree of incline of the seat.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, il-

lustrated in the accompanying drawings and specifically pointed out in the appended claims;

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a plan view of the device.

Figure 2 is a front view thereof.

Figure 3 is a rear view thereof.

Figure 4 is a side view. H

Figure 5 is a section on line 5-5 of Fig ure 1.

Figure 6 is a section on line 66 of Fig ure 1.

Figure 7 is a sectional detail view through the shifting means for the friction wheel.

Figure 85is a section on line 8-8 of Figure 2.

Figure 9 is a view showing the rail seat in the tie.

Figures 10, 11 and 12 are detail views of the cutter head.

Figure 13 is a sectional view 011 line 1313 of Figure 5 showing the driving connections from the stub shaft 26.

In Figure 9, A shows a seat which is produced by a machine constructed in accordance with this invention this seat being 0pposit ely arranged from a seat which is ordinarily formed in a tie by the pressure of a track rail thereon and which by reason of its declining outwardly causes outward inclination of the rail. The object of this in vention is to produce a seat, as shown at A, so that the rails will. incline inwardly.

In carrying out my invention I provide a frame which consists of the front 1, the rear 2 and the connecting pieces 3. An upright frame 4 is arranged adjacent the front of the machine and this frame 4 supports a moter 5, the shaft of which is provided with a pinion 6 and a pulley 7. A gear 8 meshes with the pinion and is carried by a shaft 9 which is journaled in the upright frame.- A friction wheel. is carried by a shaft 12 journaled in the upright frame and a friction disc 13 engages the faces of the members 8 and 10 so thatthe rotary movement of the gear 8 is communicated to the wheel 10. The friction disc 13 is located on a screw shaft 14 so that it can be adjusted relative to the members 8 and 10 to give the wheel 10 different speeds. The shaft 14 is geared to a manually operated shaft 15 by the gears 16, said shaft being supported in the up right frame, and has handles 17 at its ends. Thus by rotating the shaft by its handles the disc is moved towards or awayfrom the center of the wheels so that the wheel 10 can be driven at different speeds from the gear 8. The disc is guided in-its movement by means of the cross piece 18 and the guide rods 19 which are engaged by the ends of the cross piece. The wheel 10 is longitudi nally movable on its shaft 12 by means of the handlevers 20, the connections 21 and the wedge means '22 so that the said wheel 10 can be moved against the friction disc 13 or out of engagement therewith. Such means consists of a member having oppositely arranged wedges thereon and which passes through a slot in the hub of the friction wheel so that as the member moved longitudinally it will cause the wheel to move upon the shaft and thus bring it into engage ment with the friction disc. A sprocket 23 is connected with the shaft 12 and a chain 24 passes over this sprocket and a sprocket 25 on a stub shaft 26. The shaft 26 carries the sprocket 27 which is engaged by a chain 28 which also engages a sprocket 29 on one of a pair of shafts 30, these shafts being connected together by a chain 30' which passes over the sprockets on said shafts. Each.

shaft carries a. sprocket 31 which is engaged by a chain 32' which also engages a sprocket 33 connected with a flanged wheel 34, one of which is arranged at eachend of the front piece 1 of the frame. These wheels are adapted to engage the rails at one" sidenaled in the rear part 2 of the frame. Each of the shafts 42 carries a large sprocket 43 which is engaged by a tread chain 44 which in turn engages a sprocket 45 at each end of the rear frame 2. This rear frame carries the guiding rollers 46 for the tread chains, said tread chains being provided with the treads 47 which are pivoted to the links 48.

A shaft 49 is journaled in the frame and said shaft carries a pulley 50 which is connected with the pulley 7 by the belt 51 and at its rear end it is provided with a cutter head 52 which is of tapered shape, as shown. This end of the shaft is j ournaled in a sliding frame 53 which slides in a frame 54, forming part of the rear part 2, and the frame 53 is adjustable by means of'the screw shaft 55 and its handle 56.

From the above it'willrbe seen that the device is self-propelling by means of the motor, the frictionaldrive andthe chain drive from the frictional drive through the flanged wheels 34 and the tread chains 44. The wheels 34 are ad'a-ptedto engage the rails at one side of the track while the tread'chains will engage the ties on a part of the road surface. The parts are so adjusted that the cutter head will engage the ties and cut seats inthe same which slope inwardly towards the center of the tie so that the rails will be supported'at an incline which is directed in-' wardly. The inclination ofthe seat can be adjusted by means of the shafts 35,.and the handles 36 and'the depth of out can be regulated by the shaft 55 and its handle-56. The

speed of travel can also be regulated by means of the frictional drive as before explained.

I provide the cutter head with grooves 57 having curved side walls so that the cutters 58 are detaohably connected with the head by having their shanks 59 fitting in the grooves and held therein by the washers 61 and 62. I also make this head with a detachablepart 63 at its small end which is of ringshape and is held in place by the washer 61 and the grooves 64 and the tongue 65. By removing the part 63 and using cutters of short length a seat can be cut in each tie without removing the outer spikes. The cutters are reversible, thus making the cutter either right or left hand.

The cutter is made in sections, as shown in Figure 11.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

WVhat I claim is 1. An apparatus of the class described comprising a supporting frame, flanged wheels at the front thereof, means for adjusting the same vertically, endless tread chains at the rear thereof, supporting means for the chains, a motor, means'for connecting the motor with the wheels and chain supporting means, an adzing tool and means for driving the same from the motor.

2. An apparatus of the class described comprising a frame, flanged wheels at the front thereof, endless tread chains at the rear thereof, supporting means for the chains, means for adjusting the wheels vertically, a motor carried by the frame, adjustable frictional driving means actuated by the motor, means for connecting the friction means with the wheels and chains, such means including manually actuated controlling means, an adzing tool and means for driving the same from the motor.

In testimony whereof I affix my signature.

J IVILLIAM IVARREN.
